Does friction work to speed up or slow down an object?

Answer 1

The measure of friction is the amount of energy lost by heating through contact. This energy is generally lost through abrading the surfaces, or at least re-arranging the surface molecules.

Thus it will absorb kinetic energy, and the object will slow down.

Answer 2

Usually, friction will slow an object down. Here is a counter-example: if you drop something on a conveyor belt (or a similar moving object), friction between the object and the conveyor belt will make the object speed up, until it reaches the speed of the conveyor belt. Two details are worth noting:

1. In the above example, you can also say that the object still slows down, if you take its speed in relation to the conveyor belt.

2. In any case, energy is wasted, in the sense that kinetic energy is converted into heat.

Answer 3

NO! Friction con not speed up an object but it can slow down one. :)

Answer 4

Slow down

Answer 5

Yes
